Exterior light problem

2000 dodge ram 1500 3.9. 4wd light on ip flashes when left turn signal is on left front bulb dim while flashing. Ground issue but both front share same ground and right front bulb bright and right turn signal does not make 4wd indicator flash inside. Also if remove left front turn signal bulb the 4wd indicator stops flashing. Any help would be greatly appreciated.

Correct on ground issue. 12v back feeding through right turn signal and finding ground through 4wd bulb. Check the common ground wire eyelet. One ground wire is broken inside eyelet.

Paul has a video on this on a Chrysler car can't recall the model. Ground wire bundle at eyelet had the broken ground inside eyelet.

It's the left turn signal dim. Thank you for your advice. Appreciate it.

The short will be on the bright bulb ground.

It will be on the right front? That will cause dim bulb on left front and 4wd indicator on dash to flash? Correct? Thanks

Why is the left turn signal bulb dim?

I have to disagree with this.

Because the path to ground contains extra resistance, (i.e. 4WD light, and maybe more), to ground. It lacks a DIRECT path to ground.

Thanks Chad.... Scannerjohn replied that the short will be on the bright bulb ground which is the right bulb is bright and left bulb dim. Now you are saying that it is the left front bulb that is dim has a ground problem. Is that correct? Thanks.

Correct. I do not believe the problem is on the Right. I believe the problem is an open ground on the Left Bulb.

4wd light on ip flashes when left turn signal is on left front bulb dim while flashing...right front bulb bright and right turn signal does not make 4wd indicator flash inside.

It sounds, to me, like the right signal is working, as it should. It is the Left bulb that has an alternate path to ground.

I would check for voltage on the ground of all the bulbs (mainly, the Left), at the socket while the left signal is on. Front and Rear.

Sorry for any confusion on this... Does the right turn signal flash brighter than normal? and are the turns and parking lights contained in a single bulb?

Please keep me posted in what you find. I do not disagree with Chad, just interpreting thing differently.

I thought both was saying same thing. Right front Normal flashing and brightness. Let front dim but flash fast even on ip.

One of my all time favorites on the matter.

Did you find the short?

Is that ground terminal located under the window washer bottle.

Really good video:) Thanks Juergen.

Thanks I will find out next time see vehicle. Will keep you posted.
